Terror on the dance floor

Monday night’s explosion at an Ariana Grande concert in Manchester, England, that killed at least 22 and injured more than 50 is the latest in a series of recent terror attacks aimed at the West.

British Prime Minister Theresa May said the government is trying to establish the “full details” of the “appalling terrorist attack” and was expected to call an emergency cabinet meeting to deal with the horror.

But this was not the first time May, and other European leaders, have had to deal with a deadly terror attack — and the threat to the U.K. from international terrorism is severe.

Here is a timeline of recent terror attacks in Europe:

April 20, 2017: Champs Elysees Attack in Paris

An attacker got out of a car and fired an automatic weapon at a parked police van, killing the officer inside, before shooting at others standing on the nearby sidewalk, injuring two before he was shot and killed by police.

The French president said the attack was “terrorist in nature” and promised “utmost vigilance.”

The Islamic State claimed responsibility for the attack.

April 7, 2017: Stockholm Truck Attack

Five people were killed when a truck driven by a man drove into a pedestrian shopping street and department store in Sweden’s capital city, wounding over a dozen others.
